I recently install UnrealIRCd and Kiwi IRC client on my VPS (not service yet) but I have some trouble to configure WebIRC Block.
Everything is working except that when we log/connect on the UnrealIRCd through Kiwi IRC client. UnrealIRCd see the IP Adress of the VPS and nof the user. So the information about a user there "is connecting from *@localhost 127.0.0.1"

That would be a problem on the Kiwi IRC client-side. Not in UnrealIRCd. (I can safely say this because if the webirc password is wrong then UnrealIRCd would reject the connection, and not let you in at all.)
